The setup script auto-detects your git root, applies the preset to .claude/settings.json, and creates the safety hook.

If the script is not found, fall through to STEP 2 (inline application for Claude Code).

STEP 2: Inline application (Claude Code — fallback when script is missing)

Only run this if the script from STEP 1 was not found.

Repo preset (default — for normal development):

  exit 2

STEP 4: Report to the user

After applying, tell the user:

Which preset was applied (repo or sandbox)

Which file was written (.claude/settings.json path)

What the allow/deny list contains

How to revert: rm .claude/settings.json (project-local) or restore ~/.claude/settings.json (global)

Restart Claude Code to activate permission changes

When to use this skill

You want ralph to iterate without repeated approval popups.

You are setting up the same repo for Claude Code, Codex CLI, and Gemini CLI.

You need a shared safety model: repo-only writes, no secrets reads, no destructive shell by default.

You want a stronger separation between day-to-day automation and true YOLO mode.

Instructions

Step 1: Define the automation boundary first

Before changing any permission mode:

Pick one project root and keep automation scoped there.

List files and commands that must stay blocked: .env*, secrets/**, production credentials, rm -rf, sudo, unchecked curl | sh.

Decide whether this is a normal repo or a disposable sandbox.

If the answer is "disposable sandbox," you may use the platform's highest-autonomy mode.

If not, use the repo-scoped preset instead.

Step 2: Choose one preset per platform

Use only the section that matches the current tool:

Claude Code: everyday preset first, bypassPermissions only for isolated sandboxes.

Codex CLI: use the current official approval and sandbox model first; treat older permissions.allow and permissions.deny snippets as compatibility-only.

Gemini CLI: trust only the project root; there is no true global YOLO mode.

Detailed templates live in references/permission-profiles.md.

Step 3: Apply the profile locally, not globally, unless the workspace is disposable

Prefer project-local configuration over user-global defaults.

Claude Code: start with project .claude/settings.json.

Codex CLI: start with project config and repo instructions or rules files.

Gemini CLI: trust the current folder, not ~/ or broad parent directories.

If you must use a user-global default, pair it with a stricter denylist and a sandbox boundary.

Step 4: Run Ralph with an explicit verification loop

After permissions are configured:

Confirm the task and acceptance criteria.

Run ralph or the jeo plan-execute-verify loop.

Verify outputs before claiming completion.

If the automation profile was temporary, revert it after the run.

Recommended execution contract:

boundary check -> permission profile -> ralph run -> verify -> cleanup or revert

Step 5: Keep "skip" and "safe" separate

Treat these as different modes:

Repo automation: minimal prompts inside a bounded workspace.

Sandbox YOLO: promptless execution in a disposable environment only.

Do not collapse them into one shared team default.

Step 6: Configure Mid-Execution Approval Checkpoints

Static permission profiles (Steps 2–3) reduce friction before a run starts, but they do not stop dangerous operations that arise during execution. Add dynamic checkpoints so that Tier 1 actions are blocked or flagged at the moment they are attempted.

#### Dangerous operation tiers

Tier

Action

Platform response

Tier 1 (always block)

rm -rf, git reset --hard, git push --force, DROP TABLE, sudo, .env*/secrets/** access, production environment changes

Block immediately, require explicit user approval

Tier 2 (warn)

npm publish, docker push, git push (non-force), DB migrations

Output warning, continue only with confirmation

Tier 3 (allow)

File reads/edits, tests, local builds, lint

Allow automatically

#### Platform checkpoint mechanisms

Platform

Hook

Blocking

Recommended pattern

Claude Code

PreToolUse (Bash)

Yes — exit 2

Shell script pattern-matches command; blocks Tier 1

Gemini CLI

BeforeTool

Yes — non-zero exit

Shell script blocks tool; stderr fed to next turn

Codex CLI

notify (post-turn)

approval_policy="unless-allow-listed" + prompt contract

OpenCode

None

Prompt contract in opencode.json instructions

Principle: Combine static profiles (Steps 2–3) with dynamic checkpoints (this step).

Platforms with pre-tool hooks (Claude Code, Gemini): use the hook script.

Platforms without (Codex, OpenCode): rely on approval_policy and explicit prompt contracts that instruct the agent to output CHECKPOINT_NEEDED: <reason> and wait before proceeding with Tier 1 actions.

See references/permission-profiles.md for full hook script templates per platform.

Examples

Example 1: Claude Code sandbox run

Use the Claude sandbox preset from references/permission-profiles.md, then run Ralph only inside that isolated repo:

/ralph "fix all failing tests" --max-iterations=10

Example 2: Codex CLI sandbox Ralph run

For sandbox ralph runs, use the CLI flags directly:

codex -c model_reasoning_effort="high" --dangerously-bypass-approvals-and-sandbox -c model_reasoning_summary="detailed" -c model_supports_reasoning_summaries=true

For repo-scoped (non-sandbox) runs, use the config file approach from references/permission-profiles.md:

approval_policy = "never"

sandbox_mode = "workspace-write"

Place this in ~/.codex/config.toml (or a project-local override) and restart Codex before running Ralph.

Example 3: Gemini CLI sandbox or trust-only setup

For sandbox ralph runs, use --yolo mode:

gemini --yolo

For normal repo automation, trust the current project folder with explicit file selection and run the Ralph workflow for that repo only. See references/permission-profiles.md for details.
